AUTOMATIC BLAST EOLDEFJING-FURNACE.

Specification of Letters Patent.

Patented June 14:, 1921.

Application filed February 10, 1320. Serial No. 35?,5 i5.

To all to immc't may concern:

Be it known that if, CrIAnLns A. HoNns, citizen of the United States.and resident of liosedale, in the county of Nassau and State of New Yorkhave invented certain new and useful Improvements in Automatic BlastSoldering-Furnaces, of which the following is a specification.

This invention relates to an automatic blast soldering furnace. Itsobject is the production of a furnace that can be easily secured inplace, and which is made of detachable parts that look together, andwhich consequently can be easily cleaned. It has connected thereto apilot light, by virtue of which the flame of the burner of the furnacecan be turned off when work to be operated upon is being assembled, orwhen the furnace is not in actual use.

The well of the furnace is provided with a detachable abrasive restwhich protects the points of soldering irons and keeps them clean. Therest also prevents the tinning being drawn from the soldering irons.

The furnace can be made with one or a plurality of Bunsen burners, andis particularly seful for plumbing, electrical machine and general shopwork.

In the drawings Figure 1 represents a top plan view of anexemplification of the im-- proved furnace; Fig. 2 shows a fragmentarytop plan view of some of the parts of the furnace; Fig. 3 is a sectionof Fig. 1 approximately on the line 3, 3; Fig. 4; shows a left hand sideview of a portion of Fig.

1; Fig. 5 represents a left hand view of Fig. l; Fig. 6 shows aperspective view of a rest for the furnace and Fig. 7 represents aperspective view of the hood of the furnace.

The furnace is represented with the table 20, having formed therewiththe well 21 with the inclined front wall 22, the inclined rear wall 23with the lugs 24 and the side walls 25 with the flanges 26 extendingfrom the inside faces of the latter. An opening 30 in the rear wall 23has pivoted thereover a swinging door 31. A stop pin 32 extends from theouter face of the wall 23 to enable the door 31 to rest thereon when theopening 30 is to be maintained open. In the front wall 22 is formed theopening 33 to supply air for combustion. A pair of rear le s hke 36extend from a connecting brace and have formed therewith feet 38. Eachof the latter has formed therein the elongated opening 39. Bolts 40connect the brace 37 to the outer face of the well 21. in each of thelegs 36 are formed elongated openings il. A. pair of front legs l iextend from a connecting bran-e 4-5 and have formed therewith the feet46 with the elongated openings 47. Bolts 48 connect the brace 4.5 to thebottom face of the front portion (3f the table 20. in each of the legs44- are rorrned elongated openings 49 similar to 41.

Gas supply piping is shown to comprise i he side portion 52 and frontend portion 53. Clamps 54; secure the'portion 52 to the legs 36 and 37.The clamps 5% are of novel construction and each comprises the legs withthe heels A U shaped member 57 connects the legs 55. Bolts 58 extendthrough the legs and through the openmgs all and 49 to detachably clampthe legs to the legs 36 and 4A. A pair (in this instance) of Bunsenburner 61 extend upwardly and rearwardly from the front portion 53 ofthe gas supply piping through openings in the front wall 22 in the well21. Gas cocks 62 are provided for the burners. A pilot light 63 with anadjusting valve 64 extends from the portion 53 of the gas supply piping.an abrasive rest 65 in this instance of fire brick with the inclinedcorrugated table or top face 66 is located in the well 21 between therear wall 23 and the flanges 26. A detachable hood 68 which performs thefunction of a combustion chamber comprises the rear wall 69 the frontwall 70 with the opening 71 the side walls 72 each with an innerprojecting lug 73 and an outer projecting lug 74-. The hood (38 bearsupon the table 20 and detachably locks therewith by means of the saidlugs 73 and 74:. A melting or solder pot 78 has formed therewith thecurvec l'iottom l9 and from the outer surface of the latter extend lugs80 which look with the upper portions of the walls of the hood 68.

To use the furnace a soldering iron or other object to be heated islocated through the opening 71 with its end bearing on the table 66 ofthe rest 65, and at the same time lead or other material may be meltedin the melting pot 78. If desired the rest 65 may be removed and anobject may be located in the well 21 and extend through the opentings 30and 71. l

legs supporting said Welland a pair of legs supporting the front end ofthe table, gas

supply piping for the table, a detachable bracket connected to one ofeach pair of the legs supporting said piping, a Bunsen burner extendingupwardly and rearwardly. from the said piping at the front portion ofthe burner into said well, a pilot light extending from said piping intothe well and an abrasive support with an inclined top face located'insaid well. 7

nace, a detachable bracket connected to one of each pair of the legssupporting sai "oiping, a Bunsen burner extending upwardly andrearwardly from said piping at the front portion of the burner into saidwell, a pilot light extending from said piping into the well, adetachable hood locked to the table over the well and a melting potlooking with and detachably supported on the hood.

4. In a furnace the combination of a table having a well formedtherewith, a pair of legs having a pair of elongated openings formedtherein connected to the rear portion of the well, a pair of legs havinga pair of elongated openings connected to the front portion of thetable, gas supply piping with a side portion located parallel to theside of the table and a front end portion parallel to the front end ofthe table for the furnace, a pair of detachable brackets for one of eachof said pairs of legs supporting said gas piping, each of said bracketscomprising a pa1r of legs having each a heel to engage an edge of itsaccompanying leg, 2). U shaped member connecting the legs of eachbracket, bolts extending through the legs of each bracket and throughthe elongated openings in its accompanying leg of the table to securethe bracket to the leg and hold the side portion of the gas supplypining in place, a Bunsen burner connected to the front end portion ofthe piping extending upwardly and rearwardly into the well of the tableand a pilot light for the burner extending from the piping into saidwell; i
